FAN FOR RAl LWAY-CARS'.

SPECIFICATION formingpart of Letters Patent No. 510,681, dated December 12, 1893.

' Application filed January 2 6, 1893. Serial No. 45 9,786. (No model.) i

To all whom it may concern:

Be it known that I, WILLIAM J. DOUGH- ERTY, a citizen of the United States, residing at Yonkers, county of Westchester,-State of v New York, have invented certain new and useful Improvements in, Fans for Railway- Oars, of which the following is a specification. The object of my invention is to provide a fan to be carried by a railway car or other [0 vehicle and the motive power for which fan will bederived by the circulation of air caused by the passage of the car or vehicle. g

Theinvention consistsin afan located within the vehicle combined with another fan located on the outside thereof, said fans being connected together so that as the latter fan is propelled the one within the vehicle will be operated.

The invention also consists in the novel details of improvement and the combinations of parts that will be more fully hereinafter referred to and the novel features pointed out in the claims.

Referring to the accompanying drawings 2 5 which form a part of this specification Figure 1 is a side elevation of my improved fan in position on a car or vehicle, a portion of the latter being in section. Fig. 2 is an enlarged plan view, partly broken through 0 the mechanism connected with.the fan located on the outside of the car or vehicle a portion of the device being omitted to show the working parts, and-Fi g. 3 is a vertical cross section of the same.

In the accompanying drawings, the letter A indicates a portion of the car or vehicle, say the roof thereof.

B indicates a revolving head or turret suitably mounted thereon and adapted to turn 0 on its vertical axis. Forthe purpose of providing for the ease of motion I have shown the head or turret B as mounted upon abase B suitable ball bearings B being provided as shown in Fig. 3 for the purpose of reduc- 5 ing friction, but the manner of supporting the head or turret Bto rotate upon the top of the car or vehicle can be modified as desired.

The head or turretB carries several arms 0 that are provided with fans or wind blades D so arranged that as the Wind strikes them,

turret B to turn on its longitudinal axis. For the purpose of permitting the blades or fans D to be turned on the longitudinal axes to present difierent degrees of inclination to the air, the rods 0 areshown passing through and journaled in bearings or bushings E carried by the head or turret B.

E are gear wheels carried by the arms 0 within the head or turret B and adapted to mesh with toothed racks F carried by a frame orblock G located within the head or turret Band adapted to have vertical movement therein whereby when the racks F are raised or lowered the arms 0 will be turned on their longitudinal axes thereby turningthe blades D at any desired angle. But the precise means shown for turning the arms G and blades D may be varied if desired.

From the head or turret B depends a tube or rod H that passes within the car or vehicle A and at its lower part is shown journaled in a suitable bracket H carried by the car or- H and provided at its lower end with a ball or handle H and at its upper end connected with the frame or block G whereby the latter may be raised or lowered by operating the rod L from within the vehicle. By this means,

the fans or blades. D can be readily adjusted from within the vehicle without the necessity of operating them on the outside of the car or vehicle.

In order to secure the frame or block G in any desired position, I- provide the rod L with a suitable lock that may connect it with the tube H or other suitable part as shown in Fig. l. The look I have shown consists of a rack Z on the rod L to be engaged by rod or bolt m on the tube II but this construction may be varied to suit the desired purposes;

By means of my improvements, when the they will be turned and cause the heador car or vehicle travels, the fans or blades D will be turn ed. by contact with the air thereby rotating the head or turret B which'by-tnrning the tube H will rotate the fans or blades I within the car or vehicle thus agitating the air within the same. If the fans or blades D should rotate too fast it is merely necessary to raise or lower the rod L to present thesaid fans to the air at a dilferent angle.

When it is desired that the fans or blades I should not rotate, the fans or blades D should be turned horizontally to present their narrow edges to the air and for-further security the lock J will be caused to hold the tube H from rotation.

The device is simplein construction, easily operated by any person and a particular advantage is that .no special power appliances are needed for operating the fans I.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination with a car or vehicle, of a fan or blades carried thereby on the exterior thereof, a tube or extension connected with said fan or blades and passing within the vehicle, and a fan or blades connected with said tube or extension and driven thereby, and a longitudinally movable rod in said tube, and means between said rod and said fan or blades for turning said blades-at desired angles, and a lock for positively connecting the rod with the tube, substantially as described.

2. The combination of a hollow rotative head or turret, a fan or blades carried thereby and another fan or blades connected with the latter fan and driven thereby, and means withinsaid hollow headfor tnrningsaid blades on-their pivots, and a lock for positively connecting said parts together, substantially as described.

3. The combination of a rotative head or turret, a'fan or blades connected therewith and a tube or extension depending therefrom with a fan orblades connected with said tube or extension, a rod within said tube and means connecting said rod with said blades for turning the latter on their pivots, and means for positively locking said rod to said tube, substantially as described;

4. The combination with a set of fans or blades, and means for turning them simultaneously at different angles, of another set of fans or blades connected with the first mentioned set of fans, and means connecting the two sets of fans or blades for positively looking the two sets of fans or blades together in the desired position relativelyto each other, substantially as described.

5. A rotative head or turret, fans or blades having arms journaled in said head or turret and gears on said arms combined with a block or head carrying separate gears to engage respectively with the first mentioned gears, a rod to operate said block and gears, a tube connected with said head or turret and a fan or blades connected with said tube and driven thereby and means for locking said rod and tube together in the desired position, substantially as described.
